I select four columns(those are informations about payed fee for each member...so it could have zero or more rows) from my database (from two different tables), one record as "ID" and other three (i've band them together) as "Rest".Then, I've put that column "Rest" as a DisplayMember for my first ListBox...because I couldn't find a solution to put that "ID" column in the same ListBox, and make it invisible for user (I need "ID" column for accessing those fields about payed fee) I've made another ListBox and set DisplayMember = "ID".
I've put that ListBox on Visible=False and when I select rows from first ListBox "ID" is also changing and on event "SelectedIndexChange" for first ListBox I'm trying to get this "ID", store it into Integer variable and then put it into another select query that will select only selected pay fee from database...everything of this works fine but when I try to put that data from the last select query (something like this: TextBox3.Text = dataTablePodaci.Rows(0).Item(1) ) to a different textboxes (because there are three columns in select) here comes the problem, suddenly. The thing is that I can't see my real records in the main ListBox anymore...and instead of that for all rows I get:
I have this issue right now. I have a listview with checkbox. Now what I want to achieve is get all the id (hidden column) of all check items and pass it to arraylist so that I can pass it to SQL like this:
dim intProductID as new arraylist For i = 0 To lv_list_products.Items.Count - 1 If lv_list_products.Items(i).Checked = True Then
[Code].....
"DELETE * from t_products WHERE f_product_id in(" & intProductID & ")" The reason I do this is to have only one time open of database connection, One of the member suggested it is not good to open and close database specially if it is within the loop. One more issue is the command within the array I need to separate all id with commas so I will not have error on SQL.
I'm hiding the "EmployeeID", my Primary key that is part of my datagridviews datasource. I need to get the value of that hidden column of the selected row of my datagridview. How do I go about doing that?
So I have an issue with have displayed names in a listbox and trying to write a code to have a hidden price value for it. I want the selected name in the be put into another listbox as a display name and have the price value of it be in a holding value to calculate an equation.I just need help declaring the name with a value in the list box. And How do I list each listbox number so I can retrieve it back as a price value to put in a formula.
Private Sub btnAudioAddCart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAudioAddCart.Click Const decPrintIDidIt As Decimal = 11.95D 'Price of Print Book "I Did It Your Way" Const decPrintHistory As Decimal = 14.5D 'Price of Print Book "The History of Scotland" Dim intAudioInput As Integer 'Holds the selected Printed Book
I have a DataGridView which contains a hidden column. On the BindNavigator SaveItem_Click event i need to populate the hidden column cell with the current date. I tried using the DefaultValuesNeeded event but it did not work out.
I have a program and I get time data from a sqldb and display it in a column in a listbox. What are the proper steps for adding the time as I iterate through the data in the column? I figure I will need to do some conversions on the time to be able to add it and display it as a total.

I am using vs2005 with access database.In that program I have a small problem.I have joined 2 tables and get 2 column with a parametrized query.The query will work efficiently on a access database.When applying thru vs environment it doesn't do anything.I think that is a small error in my code displaying the listbox.[code]
I have a listbox with two columns. Each listbox item contains a horizontal stacked panel which in turn contains textblocks.
The listbox is empty, with each listbox item being added by the end-user through a couple of textboxes placed elsewhere. The first column accepts strings, and the second column accepts only percentages.
(I have attached a relevant portion of the event sub where a user is adding new rows.)
Private Sub btnAddItem_Click(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles btnAddSplit.Click '... Dim ListBoxItemName As New TextBlock
[Code]....
I would like to be able to check every time the above event is fired that the column of percentages does not exceed 100%. I have a couple of labels below the listbox itself where I would like to show the running total and the remainder.
My questions are:
1) How can I loop through the second column of percentages to show the running total and remainder?
2) Is there something more suitable than a ListBox that could make this easier?
I'm trying to get data from one column on my datagridview (That is reading data from an SQL Database) and put the column into a listbox.im using Datagridview as I made a program that was previously using a HUGE number of querys that make the program very inefitient when im only after one number etc, instead im downloading all the information to a datagridview object then using that for my querys then updating the database, at the minute i need to be able to manipulate the data into VB objects so the user doesnt get confused, need 1 column from datagridview to populate a listbox.

I'm trying to get the value of the third column of any row in a listbox, and this code works ONCE (It doesn't matter what column I select, I get the value), after that, and row I select has an Argument out of range exception. Here's the code:
I have filled a listbox with a column of information from my sql database
Private Sub GetClients() Dim sqlCom As SqlCommand = New SqlCommand("select emailaddress from register where paymentreceived = 'No'", sqlCon) sqlCon.Open() sqlAdapter = New SqlDataAdapter(sqlCom) sqlAdapter.Fill(sqlDS, "register") dr = sqlCom.ExecuteReader If dr.HasRows Then For Each rec As Common.DbDataRecord In dr alRows.Add(rec) Next ListBox1.DataSource = alRows ListBox1.DisplayMember = "emailaddress" End If sqlCon.Close() End Sub
But now when i try to loop through the rows of the listbox
Rather using a DatagridView Column ComboBox i need in this phase of my project, to use a listbox outside the datagridview ,o pass values from listbox to the datagridview. I do not want these Values to be default in that, column of DGV but when adding new rows i want to pass different values,always form listbox to the DGV..
I've got this working but there's something I don't understand about it. I have a DataGridView and a listbox. I want to position the listbox to be the same location as the topmost visible cell in the column the mouse is in. The end result will be that a context menu will be provided to show the user the distinct values in that column which is why I want the listbox to show over the column that it's displaying data for, just below the header cell. I'm testing right now using the CellMouseEnter event and the following code is working:
Private Sub dgvItems_CellMouseEnter(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles dgvItems.CellMouseEnter If e.ColumnIndex >= 0 Then
I am using Visual Basic 2008 Pro. I am trying to figure out how to bind a set of column headings in a DataSet (or DataGridView) to a ListBox. I want to show the column headers in the listbox control (not the data), and allow users to select one or more items
I have been trying to pull rows from my access database into a list box, so the rows do appear on the list box, however the columns are not spaced out, and when I put & Space(10) & inside the ListBox1.Items.Add() the values are all scattered around. How do I fix this?
I would like to populat the Listbox collection from a column from a Access database I already created the name of the collection as collections. I can autocomplete/Suggest a Textbox with no issues.[code]
I want the ability to auto stretch the listview control column when the form gets resized in vb.net 2008 These are the properties I am mentioning for the ListView now :
I have a listbox on my form which gets items added as the program progresses, when there are more items than the box can display, the vertical scrollbar appears, fine... so far so good.I would like the scrollbar default position to be at the bottom of it's column so that the last entered item is displayed but can't find the relevant command, I assume there is such a command.
I am wriing a vb.net windows application to log and store information. then display it in a sortable multiple column listbox (I personally like FlexGrid by Component One). However... I am not sure how to go about storing the information. Should I go with a .sdf file database, registry, simply storing them in a file, or some other method?
What I need is to be able to: read/write/delete from it read possibly up to a 20mb file and sorting it without a lot of lag be transported to multiple systems and maintain these writes (installed on many systems)
I know I could split up the reading/writing to anther thread. Even to other .DLL's and whatnot. But as for storing. Not sure what the best option is.
I've small project to do and now I'm stuck in middle. The program is to read the sequential text file and load it into a array/array of structure.The data information is like this (sample):
ID | Name | Type 1 | Cat | Animal 2 | Dog | Animal
[code]....
This is Just as sample data, my original data is more than this.I've open the DATA.txt file using FileStreamReader:
Dim FileStreamReader As StreamReader = New StreamREader(DATA.txt)
Read all the elements in the list and pass through ReadArrayString.Split the string using:
Where index 0 is the ID, index 1 is the name, and index 2 is the Type Then I load the types in the dropdown combobox menu from the array with out duplication. Like this:
If TypeComboBox.FindString(ReadArrayString(2)) < 0 Then TypeComboBox.Items.Add(ReadArrayString(2)) End If
Now When you click TypeComboBox it will show drop down menu with following list only.
Animal Bird Fish
After this, when Animal type is selected/clicked from combobox dropdown menu then it should only add the Id and Name of Animal type in the ListBox.Pseudocode may looks like this:
If Animal is selected/clicked from TypeComboBox then Add Cat into listbox Add Dog into listbox
[code]....
I've only figure out load items from only one column/array into combobox with out duplication.But can't figure out to compare the value of one column/array with another column/array and load it into listbox. I don't want to hardcode or write matching value inside the code. What I want is use the Array.
I got a problem with this code for delete button. I want it to delete the row with the listbox (lstMicro) selected item in "Microscope" column. The code below gives me an error message "Conversion from type "DataRowView" to type 'string' is not valid." What did I do wrong?
If I set a ListBox.Height = ListBox.PreferredHeight when the control is hidden and IntegralHeight = True, then set it visible:
a) Actual Height reduces by typically 3-5 pixels after redraw (but not 1 pixel per item).
b) PreferredHeight does not not appear to give the correct integral of item heights.
Is there a way to make ListBox calculate the correct integral Height before the ListBox is made visible, so it can be correctly pre-positioned from bottom edge?
